Digital Earth Africa provides a continental analysis-ready Earth observation data services. These services provide government, industry and researchers with valuable insights to help address social, environmental and economic change on the continent, develop an ecosystem for innovation and to address the challenges of sustainable development across sectors.
Digital Earth Africa's Services include:
Water Observations from Space (WOfS) is a continent-wide service that allows anyone to better understand water availability anywhere in Africa. WOfS allows users to understand the location and movement of inland and coastal water across the African continent.
It shows the presence and absence of water, and can be used to assess the change in water extent over time. This allows users across Africa to map, assess, visualise, and manage water resources and understand trends.

Crop probability over Nigeria, produced from the eastern Africa cropland extent map.
A provisional Cropland Extent Map service is now available on the Digital Earth Africa Map. It currently has coverage of areas in eastern, western and northern Africa with development of the remaining regions underway.
The cropland extent maps determine the presence or absence of crop. This information is fundamental to developing more complex agricultural products and empowers governments to understand their country’s food supply and inform decisions on a country's food security.
Consistent access to sufficient food is one of the biggest challenges facing the African continent. 33.8 million people are living with acute food insecurity in East Africa alone.

Fractional Cover is a service that describes the landscape by classifying the ground cover as bare, green and non-green. This enables analysis of environmental condition over time. The service uses Landsat 2 Surface Reflection therefore analyses can explore decades of change (back to 1980s to current day). This provides powerful insights into long-term annual as well as shorter term seasonal changes of vegetation on the Earths surface.
Fractional Cover can be used to analyse vegetation dynamics such as seasonal changes in agricultural and land practices, observe impacts of erosion and assess fuel load for estimating risk of fire.
GeoMAD is a rich data service that condenses an entire year’s worth of satellite viewing into a single cloud-free, statistically significant composite (Annual GeoMAD). A provisional semi-annual GeoMAD service is also available for Sentinel-2 data, based on a six-month time period.
GeoMAD data can be used to inform decision making on crucial sustainability issues such as water resourcing, flooding, coastal erosion, land degradation, food security and urbanisation, and is particularly useful for visualising change over time.
